Abstract:
Objective:To study the better extraction method for Qidan decoction.Method:Orthogonal design was used to find befitting conditions.The water quantity,extraction time and frequency were selected as observational conditions.The optimum conditions were repeated three times to study repetition.Results:The optimum extracting procedure is 14 times water, extracting 3 times,the time was 30 min each time.The active ingredient content RSD of three parallel trial is 0.86%.Conclusion: The optimal condition for ultrasonic extraction is 14 times water,extracting 3 times,30 min per time.This method is of good repeatability.
